It is a BEAUTIFUL name and I am SO picky when it comes to names.
My cousin had the same doubts with both of her little ones. I don't think many babies actually do 'suit' the names they've been given until they start to develop a personality and people get used to calling them by their name.
I would keep it if I were you. My Grandmother HATED the name my parents gave me when I was born but slowly fell in love with it.
Give it time - good luck.
